Sensu Core

NOTE: The time has come to announce our end of life schedule for the original version of Sensu: Sensu 1.x will reach end of life on December 31, 2019, over 8 years since its inception as an open source software project.
Read the blog post, and see the guide to migrating to Sensu Go for more information.

Sensu is the open source monitoring event pipeline built to reduce operator burden and make developers and business owners happy.
Started in 2011, Sensu’s flexible approach solves the challenges of monitoring hybrid-cloud and ephemeral infrastructures with scalable, automated workflows and integrations with tools you already use.

Monitoring for Your Infrastructure

Monitoring is the action of observing and checking the behaviors and outputs of a system and its components over time. - Greg Poirier, Monitorama 2016

Sensu is an agent-based monitoring tool that you install on your organization’s infrastructure.
The Sensu client gives you visibility into everything you care about; the Sensu server gives you flexible, automated workflows to route metrics and alerts.

Sensu is designed to monitor everything from the server closet to the cloud.
Install the Sensu client on the hosts you want to monitor, integrate with the Sensu API, or take advantage of proxy clients to monitor anything on your network.
Sensu clients automatically register and de-register themselves with the Sensu server, so you can monitor ephemeral infrastructure without getting overloaded with alerts.

Know what’s going on everywhere in your system.
Use the Sensu client to collect metrics alongside check results, then use the event pipeline to route the data to industry-standard tools like Graphite or InfluxDB.

Intuitive API and dashboard interfaces

Sensu integrates automatically with the open source Uchiwa dashboard to provide a unified view of your clients, checks, and events, as well as a user-friendly silencing tool.
The Sensu API allows you (and your internal customers) to create checks, register clients, manage configuration, and more.
